Vogt-Koyanagi-Harada disease (VKH disease) has been described in an autoimmune disease that targets melanocytes. Although VKH disease patients were often complaining of tinnitus and hearing loss, small number of the study have been reported about their hearing function. We have investigated the hearing level of 55 patients to obtain the accurate information of their hearing abilities. Almost half of the patients were diagnosed to have a sensory neural hearing loss. In general, the hearing loss in VKH disease has been known to have a good prognosis. When their hearing loss was usually mild and occurred bilaterally, it is difficult to differenciate their hearing loss from the aging. Every patient with VKH disease should be carefully observed in not only their visual function but also their hearing.
